1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Recurrent pregnancy loss (RPL) is three or more times of consecutive spontaneous loss of pregnancy. The underlying cause is complicated and the etiology of over 50% of RPL patients is unclear. In the present study, bone marrow mesenchymal stem cells were isolated from CBA/J female mice and exosomes were isolated from cell culture medium by ultracentrifugation. CBA/J female mice were paired with male DBA/2 to generate abortion prone mouse model, and CBA/J females paired with male BALB/c mice were used as control. Exosomes were injected through uterine horns into pregnant CBA/J mice on day 4.5 of gestation in abortion-prone matting. On day 13.5 of pregnancy, abortion rates were calculated and the level of transforming growth factor-β (TGF-β), interleukin 10 (IL-10), interferon g (IFN-γ), and tumor necrosis factor a (TNF-α) in CD4+ T cells and macrophages in deciduas were evaluated by flow cytometry. Exosomes injection improved the pregnancy outcomes in abortion prone mice. The IL-4 and IL-10 levels on CD4+ T cells were upregulated in the maternal-fetal interface; meanwhile, the TNF-α and IFN-γ levels on CD4+ T cells were reduced. The IL-10 level was increased and IL-12 was reduced on the monocytes that separated from deciduas. miR-101 level was increased in the CD4+ T cells in the deciduas. In conclusion, the treatment of ESCs-derived exosomes modulates T cells' function and macrophages activities in the maternal-fetal interface that resulted in a decreased embryo resorption rate, and provides a therapeutic potential to treat RPL.
